10× tested. Every lot, before it ships.

Ten separate assays, run by labs with no stake in the result. Whatever comes back goes on that lot's certificate — the measured numbers, not a summary of them.

1. PurityHPLC against a certified reference standard, reported to two decimal places.
2. Net Peptide ContentHow much peptide the vial actually holds, weighed against what the label claims.
3. IdentityHPLC retention time, read against a reference standard, confirms the molecule is the one named on the label.
4. Heavy MetalsICP-MS for lead, arsenic, cadmium, mercury and chromium.
5. SterilityA PCR screen; the certificate states whether any growth was found.
6. EndotoxinUSP <85>, published as the measured value rather than a pass mark.
7. Fentanyl ScreenChecked for fentanyl and its analogs, reported either way.
8. Product pHMeasured with a pH meter and published as the value.
9. SolubilityWhether the lot dissolves, judged by eye in the stated solvent and concentration.
10. Closure IntegrityA vacuum leak test on the sealed vial.
